OK. I am just about ready to get a DeskJet to play with (might be a good
printer for some clients). The big question is: Do any of the drivers out
there work well with a serial/parallel converter? I can't see why not, but
they might not make use of the higher speed (depends on how fast they can
build the page). I'd like to use MacPrint with a parallel cable, if it will
work well. I've got a Mac II with a cache, so there's plenty of CPU for the
driver to use. I primarily print text, but some of my clients do a lot of
graphics and page layout.

I guess none of this will matter in another nine months. System 7 will make
these kinds of printers much more attractive to the masses.
